Windows will not react to dynamically set environment variables (e.g:
`process.env.MOUNTUTILS_DEBUG = '1'`), so in order to workaround this
limitation, we set `MOUNTUTILS_DEBUG` in
`lib/child-writer/writer-proxy.js` when spawning the CLI, and we also
set `DEBUG='*'` in `lib/start.js`, so it gets picked up by the child
writer module, which spawns the writer proxy by inheriting the
environment.
After this change, the CLI becomes the only entity actually performing
I/O with the devices, and the GUI is just a wrapper around it.
When you click "Flash", the GUI spawns the CLI with all the appropriate
options, including `--ipc`, which uses an IPC communication channel to
report status back to the parent process.

This file runs the Etcher CLI if the binary was ran with
`ELECTRON_RUN_AS_NODE`, or the GUI otherwise.
